Mental Fortitude (3.5e Feat)

From D&D Wiki

Benefit: You have a Mental Damage Reduction score of 1, meaning you ignore the first point of damage from any psychic attack: this includes nonlethal damage, hit point damage, and ability damage (but not strain). Psychic abilities that don’t deal damage affect you normally and you still suffer normal damage from the indirect effects of psychic skills, such as being struck by an object thrown with Telekinesis.

Special: You can take this feat multiple times, its effects stack. So the second time you have Mental Damage Reduction 2, the third time 3, and so forth. Your Mental Damage Reduction score cannot exceed your Wisdom modifier.
